Spoiler Alert ! answer will given down below.

  Pia Cramling vs Marceline Castro, Linares 1991.

  Sweden's Cramling was the first Western-born women to hold her own against top male grandmasters.
   As a teenager, she trained with her brother Dan, also am international player and she hit the headlines at age 18 in 1982 when she has the then world number two Viktor Korchnoi on the verge of defeat.
  Here as White (to move) Cramling is a pawn down and needs fast action before her Spanish opponent can roll his Q-side pawns by a4 and b3.
  A tip: On a open board with queens and bishops, look to vary the geometrical angle of your attack, remembering that the powerful queen can easily switch from a vertical to a diagonal play.
  How did Cramling win quickly ?

  Solution:   1.Rxc7 Qxc7  2.Qd5+ e6  3.Qa8+ Kf7  4.Qf8 mate.
